How can I solve it.​
Tju [1.3M]

Step-by-step explanation:

Profit of white cement = 8 per bag

Loss of Grey cement = 5 per bag

A 3000 bags of white cement = 3000 x 8 = 24000

5000 bags of Grey cement = 5000 x 5 = 25000

So the company recieved a loss of $1000

B number of grey bags sold = 6400

= 6400 x 5 = 32000

If there are 4000 white bags = 4000 x 8 = 32000

Then there will be neither loss nor profit

What is the solution to 12x+18=4(5x-3) A. 1 1/2 B. 3 3/4 C. 7/8 D. 4/15
Olegator [25]

Answer:

B

Step-by-step explanation:

So we have the equation:

12x+18=4(5x-3)

Distribute the right:

12x+18=20x-12

Add 12 to both sides:

12x+30=20x

Subtract 12 from both sides:

30=8x

Divide both sides by 8:

x=30/8

Reduce:

x=15/4

Put into mixed fractions:

x=12/4+3/4=3\text{ } 3/4

Our answer is B :)

Answer:

Step-by-step explanation:

Jayce and Rylee are selling candy bars for a school fundraiser. Rylee sold 84 candy bars and raised $210. If Jayce raised $70, how many candy bars did he sell?

From the above question:

$210 = 84 candy bars

$70 = x candy bars

Cross Multiply

210 × x = 70 × 84

x = 70 × 84/210

x = 28 candy bars

Therefore, Jaycee sold 28 candy bars
